Surf won’t work as a field move until the 7th gym is beaten. Before that you can still use the move in battle though. This applies to other hm moves too.

As for a Pokémon agiants Tess would be any super effective choice since this would just be a story Pokémon. Since you are at frostveil you should have a few ice type Pokémon. Many dragon types are 4x weak to ice thanks to a secondary type. Though ice is frail so they die easily. Perhaps stock up on revives.

Fairy types work well too. You should have the tm for dazzling gleam

Dragon type is risky.

It wouldn’t be too hard really if you know what you are doing. I wouldn’t recommend kindler since metal claw is a fairly weak move that late into the game. Guillotine is an Ohko move but accuracy is very low. Water isn’t effective on dragon types anyway.
